  • Patent number: 11094663
    Abstract: Disclosed is a method for transient liquid-phase bonding between metal materials using a magnetic force. In particular, in the method, a magnetic force is applied to a transient liquid-phase bonding process, thereby shortening a transient liquid-phase bonding time between the metal materials, and obtaining high bonding strength. To this end, an attractive magnetic force is applied to a ferromagnetic base while a repulsive magnetic force is applied to a diamagnetic base, thereby to accelerate diffusion. This may reduce a bonding time during a transient liquid-phase bonding process between two bases and suppress formation of Kirkendall voids and voids and suppress a layered structure of an intermetallic compound, thereby to increase a bonding strength.

  • Publication number: 20210036556
    Abstract: The present disclosure provides an apparatus and method for detecting a foreign object in a wireless power transmitting system. The wireless power transmitting apparatus measures an initial transmission power transmitted from the primary core block and performs foreign object detection on the basis of the initial transmission power, once it is found that an initial voltage of an output terminal of the wireless power receiving apparatus connected to an external load is within the range of a reference voltage. By performing foreign object detection while a wireless power receiving apparatus is in an initial setting completion state, before the output of the wireless power receiving apparatus is turned on, delay in detecting foreign objects may be reduced, and a risk due to heating of a foreign object may be avoided.
